Stuck running 32-bit Windows 10? Here`s how to switch to a 64-bit version.
(Windows Phone Central)

It`s possible to use the same license to upgrade to Windows 10 64-bit from 32-bit, but it requires reinstallation. We`ll show you how to complete the task. Windows 10 can run on both 32-bit and 64-bit processor architectures. If you have a computer with a 32-bit setup, you can upgrade to the 64-bit version without acquiring a new license. The only caveat is that there is no in-place upgrade path to make the switch. The only option is to perform a clean installation of Windows 10. Although each version delivers the same features, when you upgrade to the 64-bit (x64) version, the device will be able to take advantage of large amounts of memory (up to 2TB) instead of the 4GB limitation with 32-bit (x86). The ability to access more memory allows you to run more apps simultaneously without affecting the experience, and you can work with a mix of both 64-bit and 32-bit programs. Also, and perhaps more importantly, it will help you improve productivity on memory-intensive tasks. For exam...
